Or you could just call it Readiness like blizzard did when they named it was one of the new tertiary stats they plan to add.

This, though its actually a secondary stat.

Summary of all the stuff from the blues on twitter.
Secondaries
X% Amplify means: +X% Crit Damage/Healing Multiplier and Multistrike Damage/Healing Multiplier, and +X% more Haste/Mastery/Readiness/Spirit/Armor from gear.
Multistrike is split into two (X/2)% chances, so that you can occasionally get a triple-hit (fun!), and the cap is 200%, not 100%. It also functions like Elemental Mastery (ie a new damage event of the same spell with its own chance to crit as opposed to simply being 30% of the original damage event)
X% Readiness increases the cooldown recovery rate (aka, divides the cooldown by (1+Readiness)) of *some* class abilities. The number of abilities affected by Readiness will vary by spec (will be listed in spellbook, like Mastery). Coefficient likely to vary too. Also not necessarily the same ones as the SoO trinkets and not necessarily 6 abilities per class.

haste already does that for classes that are suppossed to have this. not necessary i think. on the other hand, readyness already does this eventually.

i think theres only one class currently, that global isnt reduced with haste effects, and thats the warrior, and i strongly hope, that they will fix this. while bonusdmg can be achieved via offglobal heroic strikes, the "reaction" to casts is low on warrior, im always within a global when i need to stun that damn things ability. (silencers are off global but not everything i silence-able)

Enhancement shamans get global cooldown reduction only for Lightning Bolt and Shocks. Stormstrike, Lava Lash and Unleash Elements are uneffected.

Don't Hunters, Death Knights, Rogues and Ferals all have a fixed global cooldown of 1 second?

The way it sounds, it feels like Armor Penetration did back in Wrath--most players didn't really get the finer mechanics behind it, but knew they wanted a lot of it. Difficult to learn, easy to master.
